DETAILED DESCRIPTION

Various embodiments of the invention are disclosed herein including a target launcher 20; a target launcher system including at least one target launcher 20 and a number of other components, described in detail hereinbelow, which facilitate a variety of mounting configurations, including vehicle mount and ground stand configurations; and a target launcher system set capable of a plurality of configurations, the set likewise comprising a plurality of components and elements described in detail hereinbelow.

Referring first to FIGS. 1-3, the target launcher 20 is shown in a vehicle mount configuration 22 mounted to a conventional sleeve-like trailer hitch receiver 24 securely attached to the rear of a vehicle 26. Attachment to the vehicle 26 results in a launching platform which remains stable notwithstanding the forces involved. The trailer hitch receiver 24, as is well known, is intended to receive a drawbar (not shown) which in turn supports a hitch ball (not shown). A conventional pull pin 28 is employed in combination with the trailer hitch receiver 24 to secure whatever element is received in the sleeve-like trailer hitch receiver 24. In the FIG. 1 embodiment, a right-angled mounting adapter 30 is received in the trailer hitch receiver 24, rather than a drawbar (not shown).

The right-angled mounting adapter 30 is shown in isolation in FIG. 4, and includes an insert leg 32 which in the embodiment of FIGS. 1-3 is oriented horizontally, and is receivable in the trailer hitch receiver 24. A support leg 34 is oriented vertically in the embodiment of FIGS. 1-3. The

legs

32 and 34 are made of steel square tubing, welded together, and reinforced by a gusset 36 where joined. An aperture 38 is provided in the insert leg 32 through which the pull pin 28 passes. A pair of

mounting apertures

40 and 42 are provided in the vertical support leg 34.

FIG. 5, which is in the same orientation as FIG. 2, is a three-dimensional view showing the right-angled mounting adapter 30 of FIG. 4 received in the trailer hitch receiver 24. A mounting plate 44 is attached to the right-angled mounting adapter 30 employing a pair of

bolts

46 and 48 passing through apertures in the mounting plate 44 and through the

mounting apertures

40 and 42 in the mounting adapter support leg 34. The mounting plate 44 is oriented vertically in preparation for attachment of a single target launcher 20, the configuration FIGS. 1-3.

In FIGS. 1-3, the target launcher 20 is oriented for throwing archery targets, such as the archery target 60 which, in an exemplary embodiment, comprises a disk made by laminating circular sheets of corrugated cardboard to each other. For archery target practice, the target 60 is thrown in a manner such that the target rotates about a horizontal axis, either in a trajectory through the air (as a wing target), or bouncing and rolling along the ground (as a ground roller). However, as is described hereinbelow with reference to FIGS. 16-19, the target launcher 20 alternatively may be oriented quite differently for throwing “clay pigeons” for skeet (shotgun) target practice, where the axis of rotation of a target is more nearly vertical. Accordingly, it will be appreciated that, in the description and claims hereinbelow, terms such as “vertical” and “horizontal” are employed in a nominal sense for convenience with reference to a target launcher 20 oriented as shown in FIGS. 1-3. The same target launcher may be mounted in other orientations, in which case an element described as, for example, “vertical” with reference to FIGS. 1-3 may have some other orientation.

Thus, and referring again to FIGS. 1-3, the target launcher 20 more particularly includes a pair of spaced-apart

triangular frame members

62 and 64. The

triangular frame members

62 and 64 are essentially identical to each other and the elements thereof are described herein with reference to representative triangular frame member 62. The

triangular frame members

62 and 64 are formed generally of steel square tubing, and are of welded construction.

The representative frame member 62 includes a vertical mounting leg 66 having a mounting side 68, as well as an upper end 72 and a lower end 74. When the target launcher 20 is assembled in the configuration of FIGS. 1-3, the vertical mounting leg 66 is attached to the mounting plate 44 with the mounting side 68 against the mounting plate 44, and secured by four attachment bolts 70.

The frame member 62 additionally includes a nominally horizontal upper leg 80 joined such as by welding to the upper end 72 of the vertical mounting leg 66, and extending in a direction away from the mounting side 68 of the vertical mounting leg 66 to a far end 82 of the horizontal upper leg 80. A diagonal leg 84 extends between and is joined respectively to the far end 82 of the horizontal upper leg 80 and the lower end 74 of the vertical mounting leg 66. A junction 86 is defined where the diagonal leg 84 is joined to the far end 82 of the horizontal leg 80.

A pivot support extension 88 extends generally upwardly from the junction 86. In the illustrated embodiment, the pivot support extension 88 is simply an integral continuation of the diagonal leg 84.

A pivot element 90 is supported by the spaced-apart

triangular frame members

62 and 64 in the general location of the junctions of the diagonal legs with the horizontal upper legs. More particularly, in the illustrated embodiment, the pivot element 90 is on the pivot support extension 88 and comprises a bolt 90.

A target throwing arm 92 is supported between the

triangular frame members

62 and 64. The throwing arm 92 has first and second ends 94 and 96, and a pivot point 98 intermediate the first and second ends 96. More particularly, the pivot point 98 is near but spaced from the second end 96. The pivot point 98 cooperates with the pivot element 90 and comprises, for example, a horizontal aperture 98 through the throwing arm 92. The portion of the throwing arm 92 with the horizontal aperture 98 is made of solid one-inch square key stock, and the pivot point/aperture 98 is lined with a bronze bushing (not shown). Spacers (not visible in the drawings) are provided on either side of the throwing arm 92 to center the throwing arm 92 between the two

frame members

62 and 64, with the pivot element bolt 90 passing through the spacers. The length of the pivot support extension 88 and the positioning of the pivot element 90 are such that, in the cocked position illustrated in FIGS. 1 and 2, the target throwing arm 92 is located above and generally parallel to the horizontal upper legs 80 of the

triangular frame members

62 and 64.

During operation, the target throwing arm 92 pivots about the pivot point 98 between a cocked position as depicted in FIGS. 1 and 2 and a throwing (or thrown) position as depicted in FIG. 3. A cocking handle 100 is provided at the first end 94 of the throwing arm 92 to facilitate cocking the throwing arm 92 by moving it to the cocked position of FIGS. 1 and 2. A pair of

safety flags

104 and 106 are received in sockets 108 and 110 attached to the horizontal upper legs 80 of the

triangular frame members

62 and 64 to keep an area clear prior to the throwing arm 92 pivoting forcibly to the throwing (or thrown) position of FIG. 3.

For urging the target throwing arm 92 from the cocked position of FIGS. 1 and 2 to the throwing (or thrown) position of FIG. 3, an elastic device attachment 112 is provided at the second end 96 of the throwing arm 92. An elastic device 114, in the form of a coiled steel spring 114, also termed a main spring 114, is connected to the elastic device attachment 112. More particularly, a main spring link 116 is pivotally connected to the elastic device attachment 112, and a lower spring attachment and adjustment assembly 118 is attached to the diagonal legs 84 near the lower ends of the diagonal legs 84. The main spring 114 is in tension, and extends between the main spring link 116 and the lower spring attachment and adjustment assembly 118. The lower spring attachment and adjustment assembly 118 includes a main spring tension bracket 120 bolted to the diagonal legs 84 of the two

triangular frame members

62 and 64, and a main spring eyebolt 122 having a threaded end which passes through an aperture in the main spring tension bracket 120. For adjustment of spring tension, a threaded tension adjustment knob 124 engages a main spring eyebolt on the lower side of the main spring tension bracket 120.

A controllable latch, generally designated 126 and described hereinbelow with reference to FIGS. 6-8, is provided for holding the target throwing arm 92 in the cocked position of FIGS. 1 and 2, and releasing the target throwing arm 92 when a target is to be launched, allowing force of the main spring 114 to pivot the throwing arm 92 to the throwing (or thrown) position of FIG. 3. A latch engaging element 128 is attached to the underside of the target throwing arm 92 towards the first end 94 with the cocking handle 100. In the illustrated embodiment the latch engaging element 128 comprises an eyebolt with a triangular head.

A target holder 130 is attached to the target throwing arm 92 near the first end 94 for holding the target 60 prior to launch. The target holder 130 more particularly comprises a pair of

metal plates

134 and 136 bolted to opposite sides of the target throwing arm 92 and extending upwardly, defining a space for the target 60 in between and on top of the throwing arm 94. To facilitate a desirable degree of frictional engagement with the target 60, strips 138 of “hook” material intended as part of a hook-and-loop fastener are adhesively attached to facing inside surfaces of the

metal plates

134 and 136. Alternatively, circular pieces of indoor/outdoor carpet (not shown) may be employed. Those strips of “hook” material 138 or carpet provide sufficient frictional engagement to hold the target 60 in place prior to launch and, yet allow release of the target 60 when the throwing arm 92 pivots driven by the force of the main spring 114. Target trajectory is controlled by positioning of the target 60 along the throwing arm 92. Archery targets placed back towards the cocking handle 100 as illustrated in FIGS. 1 and 2 have a relatively more vertical trajectory (but, nevertheless, are thrown out away from the target launcher 20 with a trajectory that has a horizontal component) when launched as wing targets. Archery targets placed forward near the pivot point 98 have a flatter trajectory when launched, including ground rollers. To facilitate a range of target positions,

additional attachment apertures

140 and 142 are provided on the

middle plates

134, 136 and throwing arm 92, respectively, so that the target holder 130 can optionally be positioned closer to the pivot point 98.

With reference now to FIGS. 6-8, the controllable latch 126 is bolted to a latch base plate 160 secured to the undersides of the horizontal upper legs 80 of the

triangular frame members

62 and 64. The latch engaging element 128 includes a horizontal segment 162 supported below the target throwing arm 92 when the target throwing arm 92 is in the cocked position of FIGS. 1, 2, 6 and 8. Although the latch engaging element 128 preferably comprises a triangular eyebolt with a well-defined horizontal segment 162, it will be appreciated a round eyebolt may as well be employed, in which case the substantially horizontal segment 162 takes the form of a small arc of a circle.

The controllable latch 126 itself includes a latch receiver 164, in turn including a pair of spaced-apart

side plates

166 and 168 each defining a “V”, guide opening 170 configured at the bottom to receive the horizontal segment 162. The

side plates

166 and 168 are bolted to the latch base plate 160.

Located below the bottom of the “V” guide opening 170 is a pivot element 172 defining a pivot axis perpendicular to and extending between the

side plates

166 and 168. In the illustrated embodiment, the pivot element 172 comprises a bolt 172

apertures

174 and 176 in the

side plates

166 and 168.

A generally “C” shaped pivotable keeper 180 is located between the

side plates

166 and 168. The pivotable keeper 180 has a relatively lower pivot point 182 in the form of an aperture through which the pivot element 172 passes, an upper segment-engaging surface 184 for engaging the horizontal segment 162 of the latch engaging element 128, a top curved cam surface 185, and an actuator arm 186 extending perpendicularly to the pivot axis 172. The distal end of the actuator arm 186 is bent over to form a thumb rest 188, and an aperture 190 below the thumb rest 188 receives a quick link coupler 192 for attachment of a launch trigger cable 194. The launch trigger cable 194 is guided by a pulley 196 attached by means of an eye bolt to the mounting plate 44, in between the vertical mounting legs 66 of the target launcher 20 (FIGS. 1-3). A pair of

springs

198 and 200 urge the pivotable keeper 180 from the unlatched position of FIG. 7 to the latched position of FIGS. 6 and 8.

The controllable latch 126 additionally includes a pair of

bushings

202 and 204 on the outsides of the

side plates

166 and 168 through which the pivot bolt 172 passes for supporting the

springs

198 and 200, a pair of

brass washers

206 and 208 on either side of the pivotable keeper 180 on the inside surfaces of the

side plates

166 and 168, and a pair of

steel washers

210 and 212 to aid in retaining the

springs

198 and 200. At their upper ends, the

side plates

166 and 168 are secured to each other by

bolts

214 and 216 which secure the

side plates

166 and 168 to each other in a spaced-apart manner, aided by a stack of spacer washers 218.

During operation, the throwing arm 92 is cocked by grasping the cocking handle 100 and pivoting the throwing arm 92 until the horizontal segment 128 of the triangular eyebolt 128 engages the controllable latch 126 to achieve the latched configuration of FIGS. 6 and 8. More particularly, the throwing arm 92 is pulled down with a slight “slamming” motion which causes the eyebolt 128 to engage the top curved cam surface 185 of the pivotable keeper 180 to momentarily pivot the keeper 180 towards the released position of FIG. 7 which allows the horizontal segment 128 of the eyebolt 128 to drop into the “V” guide opening 170. The keeper 180 then returns to the cocked position of FIGS. 6 and 8 under the urging of the

springs

198 and 200, and the horizontal segment 128 of the triangular eyebolt 128 engages the segment-engaging surface 184. The throwing arm 92 is subsequently released by pulling down on the launch trigger cable 194, which pulls the actuator arm 186 down to pivot the keeper 180 sufficiently to release the eyebolt 128 from the segment-engaging surface 184.

One or more target launchers 20 may be employed in a variety of configurations as described next hereinbelow, the description concluding with a “Vehicle Mount Configuration Table” and a “Ground Stand Configuration Table” summarizing possible mounting configurations and components used in the various mounting configurations. Thus, in one aspect the invention is embodied in a target launcher system, and in another aspect the invention is embodied in a target launcher system set capable of a plurality of configurations.

With reference to FIGS. 9 and 10, a pair of

target launchers

220 and 222 are attached to the vehicle 26, in place of the single target launcher 20 of FIG. 2. In the double launcher configuration of FIG. 10, the trailer hitch receiver 24 and the right-angled mounting adapter 30 are employed as before. However, rather than the single mounting plate 44 oriented vertically, in FIGS. 9 and 10 a pair of mounting

plates

224 and 226 are secured to the mounting adapter support leg 34 of the right-angled mounting adapter 30, and are oriented horizontally. Apertures in the mounting

plates

224 and 226 enable mounting of the two

target launchers

220 and 222 side-by-side as illustrated in FIG. 10. The

target launchers

220 and 222 are mounted by their nominally vertical mounting legs 66 to the mounting

plates

224 and 226.

In the illustrated embodiments, up to six target launchers, organized as three pairs, can be attached to the trailer hitch receiver 24 and thus to the rear of the vehicle 26.

Thus, with reference to FIG. 11, a receiver expansion bar 230 is provided. It should be noted that the same element which is termed a receiver expansion bar 230 in the context of FIG. 11 in the vehicle mount configuration may also be employed for different purpose in a ground stand configuration, described hereinbelow with particular reference to FIGS. 13-15.

In FIG. 11, the receiver expansion bar 230 is oriented horizontally and has an expansion bar insert leg 232. The expansion bar insert leg 232 is best seen in FIG. 13 although, in the FIG. 13 ground stand configuration, the expansion bar insert leg 232 is not actually functional; it is a vestige of the use in the vehicle mount configuration. The expansion bar insert leg 232 extends from the receiver expansion bar 230 at a right angle and is oriented horizontally, and is receivable in the trailer hitch receiver 24 attached to the vehicle 26.

The receiver expansion bar 230 has a plurality of

expansion receivers

234, 236 and 238 oriented horizontally. The

expansion receivers

234, 236 and 238 have

openings

240, 242 and 244 facing generally in the opposite direction compared to the expansion bar insert leg 234, and serve as expansions of the trailer hitch receiver 24. Thus, each of the

expansion receivers

234, 236 and 238 is capable of receiving the insert leg 32 of a right-angled mounting adapter 30.

FIG. 12 is a top plan view illustrating the configuration where six target launchers (organized as three

pairs

250, 252, 254) are attached to the receiver expansion bar 230 and thus to the trailer hitch receiver 24. Each

pair

250, 252 and 254 of launchers corresponds to the pair of

launchers

220 and 222 in FIG. 10, and each

pair

250, 252 and 254 is secured to a respective right-

angled mounting adapter

256, 258 and 260 by a pair of horizontally-oriented mounting

plates

262, 264 and 266, like the pair of mounting

plates

224 and 226 shown in FIG. 10.

As mentioned hereinabove, embodiments of the invention can also be assembled in a portable ground stand configuration, without the use of a vehicle. FIG. 13 shows a ground stand 270 including a horizontal bar 272 having a pair of

end receivers

274 and 276, as well as an intermediate receiver 278, attached to and extending from the horizontal bar 272 at right angles. It will be appreciated that the horizontal bar 272 of FIG. 13 is the same element which is termed a receiver expansion bar 230 in FIG. 11, but used for a different purpose. Thus, the

end receivers

274 and 276 in FIG. 13 are the

expansion receivers

234 and 238 in FIG. 11, and the intermediate receiver 278 in FIG. 13 is the expansion receiver 236 in FIG. 11.

In FIG. 13, a pair of

ground support extensions

280 and 282 are received in the

end receivers

274 and 276 by passing through the hollow square sleeves, and are secured in position by a pair of pull pins 284 and 286. Each of the

ground support extensions

280 and 282 in turn includes a pair of

segments

288, 290 and 292, 294 attached to each other by

connection sleeves

296 and 298, and secured in position by pull pins 300. The expansion bar insert leg 232 serves no function in the FIG. 13 configuration.

In order to raise a target launcher a short distance above the ground for convenient more access and usage, a vertical receiver extender 310 is received in the intermediate receiver 278, and secured by a pull pin 312. The vertical receiver extender 310 is shown in isolation in FIG. 14, and includes an extender insert leg 314 oriented horizontally and received in the intermediate receiver 278, an extension segment 316 extending upwardly from the extender insert leg 314 to an extension segment upper point 318, and a sleeve-like extender receiver 320 oriented horizontally and attached to the extension segment upper point 318.

The extender receiver 320 of FIGS. 13 and 14 thus serves the same general function as the trailer hitch receiver 24 in the vehicle-mount configurations of FIGS. 1-3, 10 and 12. The

ground support extensions

280 and 282 provide sufficient stability to maintain target launchers in position despite the forces imparted during launching.

Typically, one or two target launchers are attached to the ground stand 270 basically in the same manner as the vehicle mount configurations described hereinabove with reference to FIGS. 1-3 and 10, except that, instead of the trailer hitch receiver 24, the extender receiver 320 is employed to receive a right-angled mounting adapter, such as the right-angled mounting adapter 30 shown in FIG. 4. One or two mounting plates are employed, such as the single mounting plate 44 of FIG. 2, or the pair of mounting

plates

224 and 226 shown in FIG. 10.

By way of example, FIG. 15 is a top plan view of a double launcher ground stand mount configuration, where a pair of

launchers

330 and 332 are oriented in opposite directions. In FIG. 15, the insert leg 334 of a right-angled mounting adapter 336 is received in the extender receiver 320, and a pair of mounting plates (only the upper mounting plate 338 is visible in FIG. 15) are secured to the vertical mounting adapter support leg 340. The two

target launchers

330 and 332 are secured to the mounting plates 338 by attachment to the nominally vertical mounting legs 66 of the

triangular frame members

62 and 64 of the

target launchers

330 and 332.

As an alternative to the portable ground stand 270 described hereinabove with reference to FIGS. 13-15, a permanently mounted support post (not shown) including a receiver may be secured to a concrete base.

Up to this point, target launchers embodying the invention have been described in mounting configurations suitable for launching archery targets, where a cardboard archery target rotates on a horizontal axis. As is described next with reference to FIGS. 16-19, target launchers embodying the invention may also be mounted in a sideways offset configuration for launching “clay pigeons” for skeet shooting, where the targets rotate on an axis which is more nearly vertical.

FIG. 16 shows a single-sleeve offset adapter tree 350 in isolation, and FIG. 17 shows the single-sleeve offset adapter tree 350 mounted to the trailer hitch receiver 24 in turn attached to the rear of the vehicle 26. The single-sleeve adapter tree 350 includes a horizontal insert leg 352 which is received in the trailer hitch receiver 24, a vertical support 354, and an offset receiver 356 at the upper end of the vertical support.

FIG. 18 depicts a single target launcher 20 attached via the single-sleeve adapter tree 350. In FIG. 18, a right-angled mounting adapter 30 (FIG. 4) is employed, with the mounting adapter insert leg 32 received in the offset receiver 356, and the mounting adapter support leg 34, which was nominally vertical in the configurations described hereinabove, extending horizontally, in a direction away from the vehicle 26. A mounting plate 44 is in turn secured to the mounting adapter support leg 34 and the mounting leg 66 of the target launcher 20 is secured to the mounting plate. Thus, compared to the configuration of FIGS. 1-3, in FIG. 18, the target launcher 20 is turned nearly on its side, and rotated ninety degrees so that what was the top of the target launcher in the orientation of FIGS. 1 and 2 is facing away from the rear of the vehicle in the FIG. 18 orientation.

Referring finally to FIG. 19, a double offset launcher pair configuration is illustrated, employing a double-sleeve adapter tree 360 supporting four target launchers organized as two

pairs

362 and 364. Each of the launcher pairs 362 and 364 in FIG. 19 is mounted to a respective sleeve of the dual-sleeve adapter tree 360 in the same manner as the pair of

target launchers

220 and 222 in the vehicle-mount configuration of FIG. 10.

It will be appreciated that the various components embodying the invention as described herein may be assembled in a variety of configurations. By way of example, and not limitation, the following two tables, a “Vehicle Mount Configuration Table” and a “Ground Stand Configuration Table” summarize possible configurations, to be determined by user preference.
